Improved Configurations for Dc to Dc Buck and Boost Converters

dc to dc converters are used to change the input voltage level to a desired output voltage level less (Buck converter) or more (Boost converter) than the inputvoltage magnitude. This paper proposes a novel method for increasing output power by utilizing two storage elements as well as reducing the output ripple voltage for Buck and Boostconverters. In this improved converters, two inductors are used for feeding the load by two independent switches. One inductorcharges up by the source voltage while another inductor is discharging its energy into the load during this time. Theoutput power production is almost doubled while the ripple voltage is reduced by a factor of two when compared to a conventional dc to dc converter. This paper provides theanalysis, simulation, experimental results as well as the comparison with conventional Buck and Boost converters.
